When an angle bisector is constructed for an angle of the measure, say X, then, it is divided into two equal halves, which means, two angles of measure X/2 are formed.
a) Let X = 50°. The angle bisector makes two angles of measure X2, which is 25° each. [1 mark]
b) Let X = 74°. The angle bisector makes two angles of measure X2, which is 37° each. [1 mark]
c) Let X = 105°. The angle bisector makes two angles of measure X2, which is 52.5° each. [1 mark]
